  • Automatic alignment of a 3D model to a test object
    Patent number: 10579890
    Abstract: A method of aligning a 3D CAD model to a test object in a machine vision system comprising steps of orienting the 3D CAD model in a model window, placing the test object on a motion stage in an orientation approximately matching the orientation of the 3D model, taking a video image of the test object with the video camera and extracting a peripheral boundary in a datum plane normal to the viewing axis of the video camera, extracting a silhouette boundary of the 3D model in a corresponding datum plane, relatively positioning the silhouette boundary of the 3D model to match the peripheral boundary of the test object using a fitting algorithm, and matching coordinates of points in the 3D model to coordinates of corresponding points of the test object referenced within the corresponding datum plane and along the viewing axis.
